空空导弹变结构自适应三维制导律

针对滑模变结构控制律设计中，由于系统不确定性的复杂．不确定性上限无法获知，文中利用李亚普诺夫函数构造了一个修正因子，在线的对原控制律进行修正，使原控制律对于上限不确定性具有一定的自适应，并有效地克服了抖动，大幅减小了拦截末端所需控制力。

Three-dimensional Variable Structure Guidance Law for Air-to air Missile

In order to deal with uncertain boundary of nonlinear system perturbation and disturbance during guidance law design of sliding-mode variable structure control,the Lyapunov stability theory was used to work out one correction factor by which the control system can self-correct timely.This new guidance law has adaptable capacity that it can effectively weaken system disturbance and decrease control force needed by the space terminal interception.
